Table 3: Homology between hemagglutinin gene elements present on the microarray and hemagglutinin gene sequences from the test panel. Clustal W (version 1.83) sequence analysis of test panel hemagglutinin gene sequences and hemagglutinin gene sequences present on the microarray. Only partial sequence (445 bp) was available for the HA gene from sample B (*) precluding analysis.
